PreCalculus: Unit 4 Trig Graphs

In this unit, students will:

Gain a better understanding of the unit circle and its connection to trigonometric functions. Develop an understanding of the graphs of the sine and cosine functions and learn to recognize the basic characteristics of their graphs.

Realize transformations of y = sin(x) and y = cos(x) behave just as transformations of other parent functions.

Learn that the concepts of amplitude, midline, frequency, and period are related to the transformations of trigonometric functions.

Learn how to look at a graph of a transformed sine or cosine function and to write a function to represent that graph explore several real-world settings and represent the situation with a trigonometric function that can be used to answer questions about the situation.
